The corridor on the right was silent as Xu Yinian and Xia Ziheng moved forward cautiously. Suddenly there was the sound of a door opening from behind. Xu Yinian quickly scanned the surroundings and found that there was no shelter at all.

The researcher in a white coat saw two strangers and stopped them: "Hey, you two...?"

The two looked at each other, and Xu Yinian asked calmly: "Is something wrong?"

The researcher looked at his strange face with suspicion: "Are you the new prisoners of the Black Tower? How many floors are you on?"

"Floor 189," Xu Yinian saw that he didn't seem to believe him and shook his bracelet, "Remember, we will see you again in the future, just call me brother Nian."

Xia Ziheng almost burst into tears, but managed to keep his expression calm, and pretended to show off his bracelet: "Don't block the way if you have nothing to do, I'm busy transporting people."

The researcher hesitated for a moment and clicked. Xu Yinian breathed a sigh of relief when he saw this, but noticed the communicator hidden between his fingers and the quietly moving fingers.

Xu Yinian's eyes moved slightly and his movements were astonishingly fast. Before the researcher could press the alarm, there was a sharp pain in the back of his neck. Xu Yinian caught the unconscious researcher and was about to put him down. As the researcher lost his mind,

Suddenly, his earrings lit up red without any warning!

Xu Yinian reacted: "There is actually another one??"

Sirens suddenly sounded from all directions, and the red lights buried in the wall flashed. The dark red rays like a web of light blocked the way forward in the blink of an eye, and Xu Yinian tentatively touched it with his fingertips.

A moment - Zhi! His finger was immediately cut with a small wound. He heard the footsteps coming from the corridor next door. In desperation, Xu Yinian's bloody fingertips burst out with dazzling thunder and lightning.

There was a loud bang, and the rays in the corridor were completely destroyed. At the same time, ice stretched rapidly from Xia Ziheng's feet, and the chasing patrolmen were all frozen. Xu Yinian was about to praise him for his reaction.

Quick, several dark red rays reappeared from Xia Ziheng's back, and they were about to cut Xia Ziheng's head!

Xu Yinian pushed Xia Ziheng aside violently, half of his shoulders were covered with lightning, and he punched the dense rays——

"Little Brother Xu!" Xia Ziheng's pupils narrowed.

At some unknown time, several patrolmen rushed over from the end of the corridor. The leader put his hands together and chanted a spell quickly. At the same time, a formation with complex patterns appeared at Xu Yinian's feet, because he pushed Xia Ziheng away.

, he had no time to react, and was held in place by the formation.

It's a teleportation array!

A bad premonition emerged from the bottom of his heart. Xu Yinian's eyes jumped and he was transported to a hall in an instant. The floor and walls were all spotless white. On the contrary, there was a strange and huge thing under his feet.

The red formation is like blood meandering in the snow, impartial, and he is in the center of the formation!

"Get out of there!" Hearing a familiar voice, Xu Yinian subconsciously looked towards the source of the sound. Yu Huai was staring at the formation at his feet downstairs, with a look of panic on his face that he had never seen before. There was no time to think about Yu Huai.

Why did Huai happen to be here? Just as Xu Yinian was about to do as he was told, all the bright red runes poured into his body. The severe pain made him open his eyes wide and his mind went blank.

"It's too late." At the last moment, he heard a soft voice.

Vaguely, Xu Yinian saw a pure white, snow-like monster. The monster had a face like an angel and was walking towards him with a smile.

The last set of runes penetrated into Xu Yinian's body, and a blood contract was formed. Bright red lines gradually appeared on his body, and strange lines climbed up his wrists and covered his neck, which were extremely dazzling against the white skin. Male

He fell to his knees on the ground and burst into heart-rending screams. He was shaking, struggling and twitching. It was obvious that he was in extreme pain.

"This look is much more pleasing to the eye." The doctor stood in front of Xu Yinian and commented on his miserable state. The snow demon's pure white eyes were as clear as glass, but his harsh words were completely inconsistent with his appearance.

After clapping his hands, the four closed doors in the lobby on the first floor opened one after another, and the modified experimental subjects and special prisoners poured into the room, surrounding Yu Huai.

"I arrived at the Ghost Clan five years ago and used them to complete most of the experiments, but now the research has reached a bottleneck. Those pieces of waste are not as durable as I thought..." The doctor walked to the railing on the second floor.

, looking down at Yu Huai, "Fortunately you are here. It seems that you are better than them, you should help me complete the final experiment."

Yu Huai's expression remained unchanged: "Have you started dreaming before you even closed your eyes?"

"If you don't want to save him, then I'm talking nonsense." The doctor pointed his eyes at the struggling Xu Yinian, with cruel malice in his eyes, "Without the blood of the contract owner, he will die."

Blood contracts are based on blood. After the blood contract is concluded, the contractee must obtain the blood of the contract owner at regular intervals, otherwise he will become insane, suffer torture, and finally die in unbearable pain.

The bright red runes became brighter and brighter, Xu Yinian curled up in pain, a large amount of cold sweat soaked his back, and tears of rationality dripped down his face. For a moment, the only man left in the hall was the miserable man.

Scream.

His slender fingers were clenched into fists, and the veins on the back of his hands were bulging. The gloom and violence in Yu Huai's brows could hardly be concealed. He forced himself not to look at Xu Yinian's painful struggle, and instead looked coldly at the doctor.

.

The intense killing intent was like a roiling ocean tide, overwhelming the experimental subjects surrounding him and making them unable to breathe. If given the chance, the doctor had no doubt that he would be torn into pieces by him.

It is not difficult to understand that if anyone dares to mess with his things, he will cut off the other person's hands and feet. Under the terrifying murderous intention, the smile on the doctor's lips becomes bigger and bigger: "It's scary. But you

You have found the wrong person, I am not the owner of the blood contract."

The doctor said, throwing a ‌ transparent vial down from the building: "If you take the ‌ medicine, I will save him. Don't worry, it's not a fatal thing, ‌ will make you ‌

There is no way to use force before lighting up."

The medicine bottle rolled around on the ground and stopped at Yu Huai's feet.

When the blood contract is first concluded, the blood of the contract owner must be obtained. In half an hour at most, Xu Yinian will lose his life because he cannot bear the blood contract.

"There isn't much time left for him." The snow demon upstairs seemed to be sure that he would give in and waited for his response calmly.

Time passed by, and no one in the venue dared to make any sound, lest it break the delicate situation at this moment. Yu Huai did not look at the small medicine bottle at his feet, and turned his attention to the experimental subjects and prisoners who were waiting for him.

"If I do it, these things can't stop me." His eyes finally fell on the doctor's face, with a condescending contempt in his words, "I guarantee you won't be able to walk out alive today."

The doctor's smile never faded: "Are you not going to save him? He won't be able to survive you killing everyone."

The translucent spirit body appeared in the air, and a trace of ridicule flashed in Yu Huai's eyes. The doctor's face changed slightly, and he couldn't help but feel hesitant in his heart.

Did Yu Huai give up on Xu Yinian?

After all, no matter how important the person is, it may not be as important as his own life. There are still six or seven hours until Liang Liang is at least six or seven hours away. Once he loses his strength, Yu Huai's situation will be particularly difficult.

The spirit body holding the scale circled around its owner. Several people in the circle raised their weapons, and some even leaked their strength because they were so nervous.

A huge ‌ scale appeared behind Yu Huai, and he put one hand on one end of the ‌ scale: "The power of this ‌ spirit body is to sign a contract. When both parties agree, the contract will be effective. After I take the medicine,

Xu Yinian, if something goes wrong because of the blood contract, you will die immediately."

Yu Huai's tone was cold and he said to the doctor: "Sign a contract with me, otherwise I will kill everyone present immediately."

Xu Yinian suddenly opened his eyes.

The remains of his limbs were filled with bursts of pain. His hands and feet were bound, and his whole body was fixed on the autopsy table. The scenes before he fell into coma came into his mind one after another, and he remembered that he had fallen into a blood-red formation.

Yu Huai asked him to leave, but before he could move, severe pain swept through his whole body... Where is Yu Huai?

"Stop trying your best." Seeing him struggling, a voice said coldly, "You are no different from a useless person now."

Xu Yinian turned around and found someone sitting in the shadow next to him. The man put his elbows on his knees and propped his head up to look at him. His pure white eyelashes seemed to be covered with a layer of snow, and his eyes of the same color contained a hint of snow.

A hint of sarcasm.

"Where is Yu Huai?" Xu Yinian asked.

"Waiting to die." The doctor smiled, "I should thank you properly, otherwise I wouldn't be able to deal with him——"

The tied man's eyes sharpened, and his voice suddenly turned cold: "What did you say?"

"I said, it's thanks to you, the laggard, that you fell into the blood contract formation. In order to save you, he volunteered to be my experimental subject." Seeing his expression becoming more and more terrifying, the corners of the doctor's mouth kept rising, as if he was attracted by his appearance at this moment.

Pleased, "‌It's touching. The ghost clan actually sacrificed for human beings. Did Yu Huai have no brain?"‌You kicked him in the beginning. Could it be that if he was dissected into pieces, you would die for him?

Tears?"

The doctor walked to Xu Yinian's side, bent down slightly, as if whispering: "To be honest, he can't pester you anymore. It's too late for you to be happy after getting rid of such trouble."

"...I'm going to kill you." Xu Yinian was so excited that his eyes turned red, "If you dare to touch him, I'll kill you!"

"Look at your useless look, why do you think you are still alive?" The doctor smiled, his eyebrows arched, "Because Yu Huai died for you."

After he finished speaking, he stopped looking at Xu Yinian, who looked stiff, and walked towards the door without looking back.

"Stop!!" Xu Yinian was extremely angry and shouted at the doctor's back, "Don't leave! Don't leave! Get the hell back here!"

No matter how much he scolded the snow demon, he never replied. The metal door closed tightly in front of him. Xu Yinian discovered that the bracelet used to shield the barrier was missing.

He couldn't use it. Not only that, his whole body ached due to the blood contract, and his limbs had no strength.

Xu Yinian almost went crazy when he thought that Yu Huai was in danger because he was in danger. He kept trying to mobilize the aliens, and his bound hands and feet struggled wildly, and soon they were bleeding.

Even so, he was still firmly fixed on the autopsy table. Just as he was gradually feeling desperate, the metal door suddenly made a noise.

Xu Yinian thought that the doctor had gone and returned, and his face showed a vigilant look. As the visitor approached, Xu Yinian looked stunned: "...Ye Qiao?"

It was indeed him. Xu Yinian said happily: "Ye Qiao!"

The man agreed quietly.

After not seeing each other for many days, Ye Qiao seemed to have lost some weight, and there was no color in her cheeks. He looked at Xu Yinian intently, a faint smile appeared on the corners of his pale lips: "That's great, you are indeed still alive."

Noticing his bruised and bloody wrists, Ye Qiao frowned: "You shouldn't come, it's too dangerous here."

As he spoke, he broke the shackles that bound Xu Yinian. Xu Yinian quickly asked: "How did you know I was here?"

"The alarm in the laboratory went off. I guess it has something to do with the Demon Slayer Bureau. When I saw the doctor and someone coming out of the warehouse, I followed him secretly." Ye Qiao asked, "Did you come alone?

?”

"Of course not, Chen Ran and Xia Ziheng are here." Xu Yinian did not expect to find Ye Qiao so quickly, and questions came one after another, "How are you? Are you injured? Do you still remember?

Did something happen at Bailu Mansion? You..."

"This is not the place to talk," Ye Qiao interrupted, "Where are they? I'll take you out first."
